Berserkers

Scandinavian warriors who fought in a trance-like fury.

Last updated

They were believed immune to steel and fire during these fits, but became weak afterward.[1][2] Warriors known as berserkers, who howled and foamed at the mouth while fighting in a trance-like fury, are described in an Icelandic-English dictionary from 1874.[1]

Facts from the source article.

What happened

The earliest surviving reference to berserkers is in the late 9th-century poem Haraldskvæði, which describes ulfheðnar ("wolf-skin wearers") fighting for King Harald Fairhair.[3] King Harald Fairhair used berserkers as shock troops to expand his influence.[4] They were subject to fits of frenzy called berserksgangr, during which they were thought proof against steel and fire.[1] Berserkers appear in many sagas, sometimes as elite soldiers and later as ravenous bullies.[5]

Berserkers were outlawed in Iceland in 1015.[6] According to an 1874 dictionary, during combat berserkers would howl like wild animals, produce foam from their mouths, and chew on the edges of their shields.[2] The same dictionary states that once the frenzy subsided, the berserkers became feeble and docile.[2]

What the cited sources add

That same source records berserkers in Norway as gangs of professional bullies who challenged farmers to duels and extorted ransom.[1] The National Museum of Denmark states that berserkers dedicated their lives and bodies to battle, and that their nakedness was a psychological weapon.[7] Depictions of berserkers are known from the Iron Age, and semi-naked warriors in such images are likely berserkers.[7] The Torslunda plates, found in 1870 on Öland, Sweden, show what appears to be a berserker ritual.[8]
